Hi all,
I'm lately building an amplifier for an electric microphone but I'm getting
nowhere. I tried a non-inverting amplifier-741- with a gain of 100 and then
a gain of 1000 but still there's no luck.
Sometimes I'm getting a -ve voltage (in a non-inverting amplifier!).
Also, If I connected the mic directly to a voltmeter would I get a voltage?
say, in the mV range? and if not, does it mean the mic is dead?
thx.
